This is the English translation of the Icelandic translation of Dracula.

The existence of this book is really interesting, as is the preface stuff
detailing it. So I'm glad I read this, but the book itself is weird. The
travelling to and staying at the castle section is like 60% longer than
Dracula and the rest of the book is 90% shorter. It feels astoundingly
rushed and low-stakes at the end. Oddly, kind of like Nosferatu (but even
more so).
